Hi Dave, Picture a camera mounted on top of a fixed base that pans 360 deg. back and forth. The motor connects through a circular slip ring board with brush connection. The rings are hard gold and the typical brush material is soft. Unlike the armatu

For several years now we have been using a short (4 feet) conveyor with brush wheels and a simple box fan mounted under it (blowing up) to cool the product.

Hi Ashok, Is there any rework process on those assembl./PWB ..if yes --what kind of tools are your operators using now ...brush? spudger? cloths (is it lint free?) ect. I hope you are not talking about nodules in the hole barrel. Regards Kc.

M.G. Chemicals "Safety Wash Cleaner Degreaser". A primarily ethanol / methyl alcohol product. Part number "405". Brushes, Kim Wipes, or cotton swabs have all been used from time to time to apply it to the PCB.

Static Concerns

I know that static concerns are very important in your work. Are static concerns eliminated by the antic-static devices you wear or which are in your environment, or do the hand tools you use, such as picks, tweezers and brushes, need to be anti-stat

Excess Flux in uBGA rework

Electronics Forum | Tue Sep 25 09:57:40 EDT 2001 | nwyatt

In regards to your last question, - problem is failures and most think it is due to too much flux - we apply flux with a brush - amount applied depends on the operator applying it - the flux is very thick and will hold the part in place before reflo

Excess Flux in uBGA rework

Water Residue Stains - how to remove?

Electronics Forum | Wed Dec 19 11:52:24 EST 2001 | mparker

Have you tried to polish the flex with an ESD camel hair brush? The residual films - are they organic, left over from the water? Maybe try some TSP - tri-sodium phosphate, it's a mildly caustic detergent. A thorough rinse would be needed after using

Many times after initially cleaning in the solvents recommended by the paste/material manufacturer, a light white haze may still be visable...try using a soft bristle brush to remove the remaining residues. By this time the residues that remain will
